Accurate Gas Chromatographs for Multi Component Testing
Gas chromatographs are used to separate, identify & quantify multiple components within gaseous, hydrocarbon, specialty gas & many more process streams. This highly versatile and established technology can analyse down to very low ppb levels and up to percentage levels depending on the detector used. Analysis times are generally 3-10 minutes.
ABB Measurement
ABB are an experienced supplier of analytical instruments, with over 5 decades of experience. Their range includes field gas chromatographs suitable for process applications. This includes the PGC5000 series for advanced on-line separation & analysis, the PGC1000 compact gas chromatograph for light hydrocarbon (C1-C9+) applications & the NGC8200 series for natural gas.
Where are industrial gas chromatographs used?
Industrial gas chromatographs are used when you need to know what is in your gas stream. They can be used to analyse gaseous hydrocarbon streams, natural gas, specialty gases & many more process streams. This can help make informed decisions during processes, gas quality checks & measurement applications where the amount of each individual component is important. See our Gas Stream Analyzers to see other similar products.
What should I consider Before Choosing a Gas Chromatograph??
First think about what you want to measure. Below is a list of key information to have when asking for a recommendation.
- The gas stream and the components that need to be identified or measured.
- The expected concentration range and the level of detail required.
- How often results are needed and how they will be used in process decisions.
- Sample conditions, installation location and any natural-gas metrology or custody-transfer requirements.
- The site location, because brand availability can vary by territory.
Rawson’s ABB gas chromatograph information provides further details on the PGC5000, PGC1000 and NGC8200 options. If the sample is a liquid hydrocarbon stream rather than a gas stream, see the related gas chromatographs with a liquid sample valve (LSV) page.
More information on our ABB gas chromatographs can be found below. If your sample is a liquid hydrocarbon stream please see our related gas chromatographs with liquid sample valve (LSV).
Gas Chromatograph vs other Gas Analyzers
Gas chromatography can give detailed results on multiple components in your sample. If you need to continuously monitor certain gases or a specific fuel gas property other gas analysis may be better. The correct choice will depend on what you want to measure, how quickly you need a response & how you want to use the information. To see other continuous gas analyzers please see our range. If heating value or fuel gas properties are your main requirement please see our Wobbe & calorific value analyzers.
If you have other process measurement requirements please see our Relevant Solutions for analytical instruments.
FAQs
What does ppb mean in gas analysis?
A gas chromatograph separates the components in your gas sample to identify & measure them. The range & components available will depend on the instrument & detector chosen.
Can one continuous gas analyzer measure more than one gas?
How often should a continuous gas analyzer be calibrated?
Does a continuous gas analyzer need sample conditioning?
What information should I provide when requesting an analyzer quote?
We would recommend giving us information on what type of stream you have, what compounds you want to measure, expected concentration range, how often you want to analyse, sample conditions, installation location & if there are any gas quality or custody transfer requirements. This will help us to give you a better idea of what options are suitable.
